determine encryption key without trying to decrypt

[Hauke Laging]

Hello,

how can I determine the key(s) for which a file has been encrypted without gpg 
trying to decrypt the file? I don't understand why --list-packets tries to 
decrypt it anyway. --batch and --no-tty do not solve the problem.

I don't consider my two ideas very elegant:

1) Call "gpg --status-fd $whatever --list-packets file.gpg", get the info from 
--status-fd and kill gpg

2) Start another gpg-agent, this one with --batch, and let gpg connect to this 
instance.

I cannot imagine that this cannot be done with the gpg call alone so I hope I 
just don't see the good solution.
